The EXTERN lines in elf.h already define these.
That's not a problem for most C compilers, but
apparently it is for some copies of the OS X linker.

Fixes #2167.

ast.FilterFile(src, ast.IsExported) has the same
effect as ast.FileExports(src) with this change.

1st step towards removing FileExports - it is
just a special case of FilterFile with this CL.

- Fixed Printf bug.
composition.go
- Make insertString use the same control flow as insert.
- Better Hangul and non-Hangul mixing.

There are a number of other examples that should be

In the process, rewrite index.go to use slices instead
of vectors, rewrite for-loops into range loops, and
generally simplify code (this code was written before
the launch of go and showed its age).

Also, fix a wrong import in appinit.go.

No significant performance changes (improvements);
most of time is spent elsewhere (measured on an stand-
alone MacBook Pro with SSD disk, running standard
godoc settings: godoc -v -http=:7777 -index).

ParseMediaType previously documented that it always returned
a non-nil map, but also documented that it returned a nil map
to signal an error.

That is confusing, contradictory and not Go-like.

Now it returns (mediatype string, params map, os.Error).

The subtle AST changes introduced with CL 4896053
broke type checking of type switches in gofix.
Coming up with a correct fix will take some time.
Undoing this change for now.

««« original CL description
go/parser: fix type switch scoping

The variable declared by a TypeSwitchGuard must be
visible in each TypeCaseClause and must not conflict
with other variables declared by the initial SimpleStmt
of a type switch.

Also:
- explicitly detect type switches (as opposed to detecting
  regular (expression switches) and then do extra testing
  for type switches
- fix all outstanding TODOs in parser.go
